I've had my pico plugged in for the past year at work; if you can wait, I can unplug it and do a run time test next week.
It definitely hasn't damaged the amp, as it still sounds great I guess we'll find out about the battery soon enough!
Today I completed my third workout for the week with a personal trainer. Holy crap, I'm out of shape! Really quite scary how quickly you can lose it all if you don't work at it...I've only been out of the military for two years! At least it can only get better from here.
That's a good question, because Apple likes to require the authentication chip to access the digital stream. I wonder if the USB ports on them have an authentication chip?
